' i This invention: relates, to an improved partially collapsible rim construction especially adapted for disc wheels, though not necessarily restricted thereto, and has for its object' an improved organization :ofparts by means of which, at a minimum of weight as regards the totalof material entering into themake-up of the completed article, provision: may be made for securely holding a and tireassembly,with theparts in fullyextended and positioned relation to one :another. V a p s Figure 2 is a fragmentary elevational view, bringing out the first step necessary in connectionlwith the in'drawing of the wheel and rim parts before removing the tire.

Figure 3 is a detailsectional' View taken along the line of Figure 1. 7 I H Figure 4 is an elevational viewsimilar to Figures land 2, showing a hinged portion of thetire rim retracted from itsfull tireengaging position. l

lengthwise of itself, thus drawing thehinged rim portion E out of peripheral alignment with the main rim portion B this is brought out particularly in Figure 4., The removal of the rubber tire or casing from the-thus temporarily mutilated rim is then easily effected, and as soon as a new tire orthe ren position about the rim B the restoration of the rim portion E to its former position of peripheralalignment of the rim portion B may he proceeded with, by wrench-induced swing of the lever Sin the opposite direction from that just described after Which the link Q, is taken off and the spanner rim J put in place and screwed into structural relation with the web C by means of the bolts M. The approximate degree of swing of the lever S is indicated contrastingly by the full-line and dotted-line representations of this member in Figures 2 and 4.

What I claim is:

1. A vehicle wheel having in combination,

a disc and a partly circumferential rim section secured to one side thereof, a second rim section hingedly connected at one end with the adjacent end of said first-named rim section, and a ring member adapted to engage interiorly of said rim sections when the latter are in their normal extended position, for holding said hinged rim section against centripetal swinging movement.

2. In a disc wheel assembly, in combination with the disc thereof, a plurality sectioned rim member having one of its constituent sections fixedly carried by the peripheral edge of I said disc and another of its sections hingedly connected at one end to the adjacent end of t the first-mentioned rim section, a removable rim and tire-engaging spanner adapted to engage interiorly of said rim sections, when the latter are in positions of circular align-. ment, and means formed on said disc and said second named rim section, adapted to receive removable manipulating means whereby the second mentioned rim section may be drawn away from its described position of circular alignment with the first-mentioned rim section after the removal of said spanner has been effected.

3. In combination with a wheel'disc and a partly circumferential rim section connected therewith, a plurality of rim sections hingedly connected with each other, and one of which is hingedly connected at one end with said first-named rim section, said rim sections being in substantial alignment, when in 0perative position, with the peripheral edge of said wheel disc, means for locking the parts in such position, comprising an annular bracing member and means formed on'said disc and on a hinged rim section adapted to re ceive removable manipulating means whereby the hinged rim section may be indrawn preparatory to the positioning about or removal from the periphery of the wheel of a tire member.

41. In combination with a rim for a vehicle wheel, comprising a plurality of hingedly connected sections having a pair of abutting free ends, a disc member with which one of said rim sections having a free end is fixedly connected, means for structurally associating the other rim sections with said disc member when the former are in extended position, and for securing the same, comprising an annular bracing member, and means formed on said disc and on one of the hinged rim sec tions to receive removable; manipulating means for effecting the inward, and/or out-- ward swing of said hinged rim sections'to enable removal of a tire from the rim as a whole or mounting of the samethereon.

5. In combination with a disc, a plurally sectioned rim member having its periphery in substantial alignment with the periphery of said disc, a certain section of the rim'being fixedly carried thereby and another of the component sections of the rim being hingedlyconnected at one of its ends with the adjacent end of the fixed portion of the rim in position for actuated inward swing from its normal position of truly circular coincidence therewith, a removable spanner member of substantially the same peripheral size and contour as the inner surface of the component sections of the rim when in extended position, adapted to be positioned interiorly thereof and against the adjacent face of the disc, to hold the rimsections in their described extended position.

In testimony whereof I sign this specification.

GEORGE CHRISTIA.
